Wavin OsmaS ABS Air Admittance Valve Grey 110 mm 4S306G

The Wavin OsmaS ABS air admittance valve in grey, 110 mm (code 4S306G), is an above-ground soil and vent system product. It allows air into the discharge pipework under reduced pressure, protecting water seals in appliance traps, and closes under positive pressure to stop foul air escaping into the building.

It is designed for use in above-ground drainage systems rather than below-ground drainage, and is intended to be installed by a competent general builder or contractor on domestic or non-domestic stacks. The valve is ABS with a synthetic rubber diaphragm and connector, and can be push-fitted to 110 mm pipe or solvent-welded when the connector is removed.
